本申请涉及到电子设备技术领域,尤其涉及到一种血压测量设备及电子设备。
当今人们越来越重视自身及家人的健康情况,血压测量在其中也显得尤为重要。随着科技的进步与发展,不仅出现了家庭用的血压测量设备,在一些可穿戴设备(例如智能手表或者智能手环等)中也开始集成血压测量功能,其为用户随时随地进行血压测量提供了可能性。
目前的血压测量设备,均是直接将微泵和压力传感器置于血压测量设备的主体内部。压力传感器可通过对血压测量设备的气压进行测量,来获得用户的血压值。但是,在应用该血压测量设备进行血压测量的过程中,由于微泵会将主体内部的气体充入气囊,充气过程中会产生气流,气流会造成气压波动,从而造成压力传感器检测到的气压不稳定,影响血压测量设备测量得到的血压值的准确度。
因此,如何提供一种能够满足血压测量精度的血压测量设备已成为本领域技术人员亟待解决的难题。
发明内容
本申请提供了一种血压测量设备及电子设备,以减小血压测量设备的内部气压对于其血压测量的影响,从而提高血压测量的精度。
第一方面,本申请提供了一种血压测量设备,该血压测量设备可以包括主体、处理器、气囊、供排气装置、驱动装置、气压传感器和流量计。其中,主体包括一个腔体,血压测量设备的各功能模块或者器件可以设置于该腔体内,例如上述的驱动装置、处理器、供排气装置、气压传感器可设置于腔体内。气囊固定于主体的一个端部,且气囊具有气腔。供排气装置包括进气气路和泄气气路,且供排气装置通过第一气路与气囊的气腔相连通。气压传感器可以通过第二气路与气囊的气腔相连通,从而可以检测气腔内的气压值。流量计用于检测供排气装置与气囊相流通的气体的气体流量值,或用于检测气压传感器与气囊相流通的气体的气体流量值。血压测量设备中存储有气体流量值与气压补偿值的对应关系,例如存储于处理器中。处理器与气压传感器、流量计以及驱动装置电连接,处理器可以根据流量计检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系获得气压补偿值,从而可以根据获得的气压补偿值对气压传感器检测的气压值进行补偿,进而可以根据补偿后的气压值控制驱动装置。而驱动装置与供排气装置电连接,用于在处理器的控制 下驱动供排气装置进行充气或放气。
采用该血压测量设备进行血压测量时,在供排气装置对气囊进行充放气时,由于供排气装置与气囊以及气压传感器三者之间的气体是流通的,因此通过流量计检测到的气体流量值可以用来表征供排气装置的充放气量,从而处理器根据流量计检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,得到较为准确的气囊内的气压值。进而可以减小血压测量设备在充放气过程中对血压测量的影响,提高血压测量的精度。
在本申请中,为了方便流量计检测供排气装置与气囊相流通的气体的气体流量值,流量计可以设置于第一气路上,以用于检测第一气路中的气体流量值。或者,为了方便流量计检测供排气装置与气压传感器相流通的气体的气体流量值,流量计可以设置于第二气路上,以用于检测第二气路中的气体流量值。

需要说明的是,在本申请中,当血压测量设备还包括气路腔体时,流量计也可以设置在第三气路上,以用于检测第三气路中的气体流量值。这样,流量计检测到的气体流量值既可以是供排气装置与气囊相流通的气体的气体流量值,也可以是供排气装置与气压传感器相流通的气体的气体流量值。
在本申请一个可能的实现方式中,为了将气囊与主体进行连接,可以在主体的端部设置有一个连接孔。另外,气囊具有一个气嘴,气嘴自气囊的一侧表面沿朝向主体的方向凸出于气囊。这样,即可通过气嘴插接于连接孔,且将第三气路与气嘴连接,来实现气囊与气路腔体的连通。相类似的,在另外一些可能的实现方式中,还可以将气嘴设置于主体的端部,而在气囊上设置连接孔,这样也可以通过气嘴与连接孔的插接来实现气囊与主体的连接。

在本申请中,气体流量值与气压补偿值的对应关系可以预先通过对预先测试的数据分析得到,并可以在血压测量设备出厂前预先存储在血压测量设备中的处理器或存储器中。
示例性的,在本申请中,处理器可以通过如下方式获取气体流量值与气压补偿值的对应关系:首先控制血压测量设备在卸除气囊的情况下进行充气,以使流量计检测到的气体流量值发生变化;并且获取流量计在检测到多个不同的气体流量值时气压传感器检测到的多个气压值,并将获取到的多个气压值作为该多个不同的气体流量值分别对应的气压补偿 值;最后根据多个不同的气体流量值和其分别对应的气压补偿值,建立气体流量值与气压补偿值的对应关系。
示例性的,处理器可以根据多个不同的气体流量值和其分别对应的气压补偿值,通过插值法建立气体流量值与气压补偿值的对应关系。

其中,血压测量设备进行血压测量的流程可以包括:控制驱动装置驱动供排气装置向气囊充气,然后读取气压传感器检测的气压值和流量计检测的气体流量值,然后根据流量计检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,具体可以将气压传感器检测的气压值减去获得的气压补偿值从而得到补偿后的气压值,然后根据补偿后的气压值控制驱动电路的工作参数(例如电压,电流,频率等)驱动供排气装置向气囊充气。执行上述流程至少一次,例如1次、2次、3次或4次等,使补偿后的气压值满足血压测量所需的升压曲线要求,从而完成血压测量。

本申请中,由于气腔内气体波动是由供排气装置充放气产生的,距离供排气装置越近的区域,产生的气压波动越大,因此,第二气压传感器可以靠近供排气装置设置,第二气压传感器距离供排气装置越近,测量结果越准确。

为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述。
为了方便理解本申请实施例提供的血压测量设备,下面首先说明一下其应用场景。该血压测量设备可以但不限于为医用、家用等体积较大的用于血压测量的设备,也可以为智能手表、智能手环等便携性的带有血压测量功能的电子设备。以智能手表为例,其可以佩戴于用户的腕部,以能够随时检测用户的血压等身体体征,以实现对身体状态的预知,从而可有效的避免高血压引起的中风等危险继发症。
参照图1,图1为本申请一种实施例提供的带有血压测量功能的智能手表的结构示意图。带有血压检测功能的血压测量设备,一般可以包括主体1和气囊2,气囊2可固定于主体1的一个端部。示例性的,气囊2可以固定于主体1的底面的一个端面。在本申请中, 主体1的底面是指智能手表在佩戴于腕部时,主体1直接与腕部接触的表面。另外,血压测量设备还可以包括腕带3,如图1所示,气囊2可位于腕带3的朝向用户的腕部的一侧。这样,在腕带3绕于用户的腕部时,可以将气囊2压向腕部,并使其与腕部相贴合,从而便于实现对用户的血压的测量。可以理解的是,气囊2与腕带3可以但不限于通过卡接、粘接或者铆接等方式相固定,以减少气囊2与腕带3之间相互移动产生的摩擦力,从而降低气囊磨损的风险,以提高血压测量设备的使用寿命。
带有血压测量功能的智能手表,除了包括上述结构外,通常还可以设置有光电容积描记器(photoplethysmograph,PPG)模块。其中,PPG模块102也可以设置于主体1的底面,另外,还可将PPG模块102设置于主体1的底面的中间区域(参见图1所示主体1的底面中间圆形区域),以便于提高PPG模块102的检测准确性。由于PPG模块102可实现对人体的心率值进行连续的测量,通过在智能手表上同时设置气囊2和PPG模块102,可将利用气囊2进行单次血压测量的功能与PPG模块102的连续心率测量功能进行集成,并通过精确的算法运算解决连续血压测量的难题。
可继续参照图1,本申请实施例的智能手表还可以同时设置有心电图(electrocardiogram,ECG)检测模块103,该ECG检测模块103也可以设置于主体1的底面,另外,还可将ECG检测模块103设置于主体1的中间区域,其示例性的可以设置于PPG模块102的周侧(参见图1所示主体1的底面中间两个弧形区域),从而实现智能手表的心电图检测功能。
可一并参照图2,图2展示了一种传统的血压测量设备的框架结构示意图。其中,主体1具有腔体101,血压测量设备的主要功能模块以及器件(例如处理器和传感器等电路元器件)可设置于主体1的腔体101内,例如,供排气装置4、气压传感器5、驱动装置6和处理器7等。气囊2的一端可通过气嘴与供排气装置4和气压传感器5连通,气囊2可绕于用户的腕部。在使用该血压测量设备进行血压测量时,处理器7控制驱动装置6驱动供排气装置4对气囊2进行充放气,而气压传感器5可检测气囊2中的气压在上述充放气过程中的变化,这样,可通过算法对检测到的气压值进行运算得到用户的血压值。
由上述对血压测量设备进行血压测量的过程的介绍可以理解,由于供排气装置4设置于主体1的腔体101内,在供排气装置4对气囊2进行充放气的过程中,会造成主体1的腔体101内的气压的波动,该气压的波动会造成气压传感器5检测到的气压值与气囊2内部的实际气压值不同,且一般气压传感器5检测到的气压值大于气囊2内部的实际气压值。
基于此,本申请实施例提供了一种血压测量设备,以减小血压测量设备的主体1的腔体101内的气压对于其血压测量的影响,从而提高血压测量的精度。为了便于理解,在本申请以下实施例中,以智能手表为例对该血压测量设备的具体结构进行详细的说明。

参照图3和图4,图3为本申请的一个实施例提供的血压测量设备的框架结构示意图,图4为本申请的另一个实施例提供的血压测量设备的框架结构示意图。在本申请该实施例中,血压测量设备可以包括主体1和气囊2。其中,主体1具有多个侧壁,该多个侧壁相连接,以围设形成主体1的腔体101,在主体1的腔体101内可设置有该血压测量设备的主要功能模块和器件。气囊2可固定于主体1的一个侧壁,且气囊2具有气腔。
可继续参照图3和图4,在本申请该实施例中,血压测量设备还可以包括供排气装置4和气压传感器5,该供排气装置4和气压传感器5均设置于主体1的腔体101内。其中,供排气装置4包括进气气路401和泄气气路402,该进气气路401和泄气气路402均与主体1的腔体101相连通。另外,供排气装置4还通过第一气路81与气囊2的气腔相连通。这样,主体1的腔体101内的气体可通过进气气路401进入供排气装置4,并通过第一气路81进入气囊2,从而实现供排气装置4对气囊2的充气。相反的,当气囊2中的气体需要排出时,供排气装置4通过第一气路81将气囊2中的气体抽出,并经泄气气路402排放到主体1的腔体101。
另外,由于供排气装置4的进气气路401和泄气气路402不同时工作,因此,在本申请一个可能的实施例中,可以将进气气路401和泄气气路402合并设置,即只在供排气装置4上设置一条气路,供排气装置4可通过该气路对气囊2进行充气,并可使气囊2内的气体经过该气路抽出,从而可简化血压测量设备的结构。
在本申请中,不对供排气装置4的具体结构进行限定,示例性的,该供排气装置4可以为气泵,气泵的体积可根据血压测量装置的气囊2对于供排气的需求以及主体1的腔体101的大小进行设置。又考虑到目前带有血压测量功能的智能手表,其主体1的体积较小,则其腔体101的空间也较小,因此,设置于智能手表中的气泵的体积也较小。在本申请一些可能的实施例中,可将气泵固定于一个结构件(图中未示出)上,然后通过该结构件与主体1的固定来实现气泵在主体1上的安装。该结构件的材质可以但不限于为金属或者强度较大的非金属,以使其能够对气泵起到可靠的支撑,从而提高气泵的结构可靠性。在本申请中,不对气泵与结构件之间的固定方式进行限定,示例性的,可通过点胶或者螺纹联接等方式进行固定连接。另外,在本申请一些实施例中,还可以在气泵的周围进行点胶,以对气泵进行胶封,以此来提高气泵的结构稳定性。
可继续参照图3和图4,血压测量设备还可以包括驱动装置6和处理器7,且处理器7分别与驱动装置6和气压传感器5电连接。在本申请中,对驱动装置6和处理器7的位置不作限定。示例性的,可以将驱动装置6和处理器7设置在主体1的腔体101内。处理器7用于对气压传感器5和驱动装置6进行控制,驱动装置6用于在处理器7的控制下为供排气装置4的充放气过程提供驱动力,在本申请中,也不对驱动装置6进行具体的限定,示例性的,可为电机等。气压传感器5用于在处理器7的控制下进行气压检测,在本申请中,也不对气压传感器5进行具体的限定。在本申请中,由于供排气装置4是设置于主体1的腔体101内,在供排气装置4对气囊2进行充放气的过程中,会造成主体1的腔体101 内的气压的波动,该气压的波动与供排气装置4的充放气量相关,如果能够获取由该充放气量造成的气压传感器5的气压值的改变,那么就可以对气压传感器5检测到的气压值进行误差补偿,从而减小血压测量设备的主体1的腔体101内的气压对于其血压测量的影响,提高血压测量的精度。
因此,可继续参照图3和图4,血压测量设备还可以包括流量计9。流量计9用于检测供排气装置4与气囊2相流通的气体的气体流量值,或用于检测气压传感器5与气囊2相流通的气体的气体流量值。血压测量设备中存储有气体流量值与气压补偿值的对应关系,示例性的,该对应关系可以存储于处理器7中或存储器中,处理器7可以根据流量计9检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系获得对应的气压补偿值,从而根据获得的气压补偿值对气压传感器5检测的气压值进行补偿,进而可以根据补偿后的气压值控制驱动装置6。驱动装置6在处理器7的控制下驱动供排气装置4充气或放气,即驱动装置6可用于为供排气装置4的充放气过程提供驱动力。
由此可知,在本申请中,在供排气装置4对气囊2进行充放气时,由于供排气装置4与气囊2以及气压传感器5三者之间的气体是流通的,因此通过流量计9检测到的气体流量值可以表征供排气装置4的充放气量,从而处理器7根据流量计9检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器5检测的气压值进行补偿,得到较为准确的气囊2内的气压值。进而可以减小血压测量设备在充放气过程中对血压测量的影响,从而提高血压测量的精度。
在本申请中,为了方便流量计9检测供排气装置4与气囊2相流通的气体的气体流量值,示例性的,参见图3,流量计9可以设置于第一气路81上,以用于检测第一气路81中的气体流量值。或者,在本申请中,为了方便流量计9检测供排气装置4与气压传感器5相流通的气体的气体流量值,示例性的,参加图4,流量计9可以设置于第二气路82上,以用于检测第二气路82中的气体流量值。
本申请中,由于气腔内气体波动是由供排气装置4充放气产生的,距离供排气装置4越近的区域,产生的气压波动越大,因此,将流量计9设置在距离供排气装置4较近的第一气路81上相比设置在第二气路82上可以提高测量的准确性。
在本申请各实施例中,不对各气路的具体设置形态进行限定,其可以呈直线设置,也可以呈曲线设备,具体可以根据血压测量设备的内部空间的部件进行适应性的调整。可以理解的是,为了使图示清楚,在本申请各示意图中,均将各气路示意为直线。
参照图5和图6,图5为本申请另一个可能的实施例提供的血压测量设备的框架结构示意图,图6为本申请另一个可能的实施例提供的血压测量设备的框架结构示意图。图5和图6所示的实施例的血压测量设备与上述图3和图4所示的实施例的不同之处主要在于:在图5和图6所示的实施例中,血压测量设备还包括气路腔体10,该气路腔体10设置于主体1的腔体101内。另外,该气路腔体10可以但不限于通过粘接或者螺纹联接的方式固定于主体1的侧壁朝向腔体101的一侧,以提高气路腔体10的结构稳定性。
基于血压测量设备的结构的上述变化,在本申请该实施例中,气压传感器5和供排气装置4与气囊2之间的连接方式也做了适应性的变化。具体实施时,可继续参照图5和图6,供排气装置4通过第一气路81与气路腔体10连通,气压传感器5通过第二气路82与气路腔体10连通。这样,第一气路81和第二气路82可通过气路腔体10进行连通。另外,气路腔体10可通过第三气路83与气囊2的气腔连通。图5和图6所示的实施例的血压测 量设备的其它结构均可参照上述任一实施例进行设置,在此不进行赘述。
采用本申请该实施例提供的血压测量设备,通过增加气路腔体10的设计,可通过气路腔体10将供排气装置4的进气气路401和泄气气路402与气囊2的气腔连通。当供排气装置4工作时,该供排气装置4可把气体从主体1的腔体101吸入到气路腔体10,随后进入气囊2的气腔。另外,供排气装置4还可通过将气路腔体10内的气体由泄气气路402排出,来实现气囊2内的气体的排出。
在本申请一个可能的实现方式中,为了将气囊与主体进行连接,可以在主体的端部设置有一个连接孔。另外,气囊具有一个气嘴,气嘴自气囊的一侧表面沿朝向主体的方向凸出于气囊。这样,气囊即可通过气嘴插接于连接孔,且将第三气路与气嘴连接,来实现气囊与气路腔体的连通。相类似的,在另外一些可能的实现方式中,还可以将气嘴设置于主体的端部,而在气囊上设置连接孔,这样也可以通过气嘴与连接孔的插接来实现气囊与主体的连接。
值得一提的是,在本申请中,气囊与主体之间可为可拆卸连接,这样,可根据需要对气囊进行拆卸或者更换等。另外,在本申请一个可能的实现方式中,血压测量设备还可以包括光电容积描记器PPG模块和ECG检测模块,该PPG模块与ECG检测模块可以设置于主体的底面。而气囊也可以与主体的底面的一个端部固定连接,从而在使血压测量设备集成多项测量功能的同时,使该血压测量设备的结构较为紧凑。
参见图7,图7为本申请另一个可能的实施例提供的血压测量设备的框架结构示意图。当血压测量设备还包括气路腔体10时,流量计9也可以设置在第三气路83上,用于检测第三气路83中的气体流量值。这样,流量计9检测到的气体流量值既可以是供排气装置4与气囊2相流通的气体的气体流量值,也可以是供排气装置4与气压传感器5相流通的气体的气体流量值。值得一提的是,图7所示的实施例的血压测量设备与上述图5和图6所示的实施例的血压测量设备相比,仅是流量计9的位置不同,工作原理是相同的。图7所示的实施例的血压测量设备的其它结构均可参照上述任一实施例进行设置。
参见图8,图8为本申请实施例的一种血压测量设备的血压测量方法,在该血压测量设备中主要包括主体、气囊、气压传感器和流量计;其中,主体包括腔体,气压传感器位于腔体内,气囊具有气腔,气腔与腔体相连通,流量计用于检测血压测量设备进行充放气时的气体流量值,气压传感器用于检测气腔内的气压值;该血压测量设备的具体实施可以参见上述图3至图7所示的实施例的血压测量设备,在此不作赘述。如图8所示,该血压测量设备的血压测量方法可以包括以下步骤:
S101、获取血压测量设备进行充放气时流量计检测的气体流量值和气压传感器检测的气压值。
S102、根据气体流量值以及存储的气体流量值与气压补偿值的对应关系获得对应的气压补偿值。
S103、根据获得的气压补偿值对气压值进行补偿。
由此可知,在进行血压测量时,可以根据流量计检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,得到较为准确的气囊内的气压值。进而可以减小腔体内的气压对于血压测量的影响,从而提高血压测量的精度。
在本申请中,气体流量值与气压补偿值的对应关系可以预先通过对预先测试的数据分 析得到,并可以在血压测量设备出厂前预先存储在血压测量设备中的处理器或存储器中。
示例性的,如图9所示,处理器可以通过如下方式获得气体流量值与气压补偿值的对应关系:步骤S201、控制血压测量设备在卸除气囊时进行充气,以使流量计检测到的气体流量值发生变化。
将血压测量设备中的气囊卸除,可以使主体的腔体与外界大气连通,从而保证气压传感器检测的气压值不受气囊内气腔气压的影响,主要是由腔体内气流波动产生的。
在具体实施时,可以控制驱动装置使流量计检测到的气体流量值由最小值变为最大值。
步骤S202、获取流量计在检测到多个不同的气体流量值时气压传感器检测到的多个气压值,并将获取到的多个气压值作为该多个不同的气体流量值分别对应的气压补偿值。
其中,该多个不同的气体流量值可以从零至最大气体流量值之间进行选择,例如流量计检测到的气体流量值的最大值为100ml/min,则可以在0~100ml/min之间,选择多个气体流量值,示例性的,选择的气体流程值可以是呈等差分布的,例如0ml/min、10ml/min、20ml/min、30ml/min、40ml/min、50ml/min、60ml/min、70ml/min、80ml/min、90ml/min、100ml/min。可以理解的是,选择的气体流量值越多,后续得到的气体流量值与气压补偿值的对应关系越准确。
在具体实施时,可以在流量计检测到的气体流量值为q1时(例如0ml/min),获取气压传感器检测到的气压值Δp1,将Δp1作为q1对应的气压补偿值。示例性的,可以将Δp1记录并存放在存储器中,供后续使用。然后增大气体流行,至流量计检测到的气体流量值为q2时(例如10ml/min),获取气压传感器检测到的气压值Δp2,将Δp2作为q2对应的气压补偿值。示例性的,可以将Δp2记录并存放在存储器中,供后续使用。然后增大气体流行,至流量计检测到的气体流量值为q3时(例如20ml/min),获取气压传感器检测到的气压值Δp3,将Δp3作为q3对应的气压补偿值。示例性的,可以将Δp3记录并存放在存储器中,供后续使用。以此类推,从0至最大气体流量选择N个不同的气体流量值:q1、q2、q3、q4、……、qN,获取对应的气压补偿值Δp1、Δp2、Δp3、Δp4、……、Δp N。其中,qN可以取最大气体流量值。
步骤S203、根据多个不同的气体流量值和其分别对应的气压补偿值,建立气体流量值与气压补偿值的对应关系。
示例性的,处理器可以根据多个不同的气体流量值和其分别对应的气压补偿值,通过插值法建立气体流量值与气压补偿值的对应关系。
参见图10,对于位于q1至q2、q2至q3、……、qN-1至qN之间的气体流量值q(x),例如q(x)位于qi至qj之间,那么q(x)对应的气压补偿值Δp(x)可以根据公式Δp(x)=Δpi+[q(x)-qi](Δpj-Δpi)/(qj-qi)确定,其中,i可以取遍1至N-1中的任意数,j=1+1。
在具体实施时,对于位于0至q1、q1至q2、q2至q3、……、qN-1至qN之间的气体流量值q(x)所对应的气压补偿值Δp(x)也可以通过其它方式确认,例如q(x)位于qi至qj之间,那么q(x)对应的气压补偿值Δp(x)=(Δpj-Δpi)/2。其中,i可以取遍1至N-1中的任意数,j=1+1。
由上述可知,正是存储了预先建立的气体流量值与气压补偿值的对应关系,这样在进行血压检测时,就可以根据流量计检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,得到较为准确的气囊内的气压值。其中,血压测量设备进行血压测量的流程可以包括: 控制驱动装置驱动供排气装置向气囊充气,然后读取气压传感器检测的气压值和流量计检测的气体流量值,然后根据流量计检测的气体流量值以及存储的气体流量值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,具体可以将气压传感器检测的气压值减去获得的气压补偿值从而得到补偿后的气压值,然后根据补偿后的气压值控制驱动电路的工作参数(例如电压,电流,频率等)驱动供排气装置向气囊充气。执行上述流程至少一次,例如1次、2次、3次或4次等,使补偿后的气压值满足血压测量所需的升压曲线要求,从而完成血压测量。
需要说明的是,在本申请中,不限于利用流量计直接来检测血压测量设备进行充气时的气体流量,还可以采用间接能反应气体流量的其它传感器来代替流量计,例如利用气压传感来实现。具体可以参见下面实施例。
参照图11,图11为本申请另一种实施例提供的血压测量设备的结构示意图。该实施例的血压测量设备的结构与上述任意实施例均有不同,其不同之处主要在于:在该血压测量设备中不包括流量计,而是包括两个气压传感器即第一气压传感器5a和第二气压传感器5b。在该血压测量设备中,第一气压传感器5a和第二气压传感器5b均设置于腔体101内;第一气压传感器5a可以通过第二气路82与气囊2的气腔相连通,用于检测气囊的气腔内的气压值;第二气压传感器5b用于检测主体1的腔体101内的气压值;血压测量设备中存储有腔体气压值与气压补偿值的对应关系,例如可以存储于处理器或存储器中。处理器7与第一气压传感器5a、第二气压传感器5b以及驱动装置6电连接,用于根据第二气压传感器5b检测的气压值以及血压测量设备中存储的腔体气压值与气压补偿值的对应关系获得对应的气压补偿值,再根据获得的气压补偿值对第一气压传感器5a检测的气压值进行补偿,并根据补偿后的气压值控制驱动装置6;驱动装置6与供排气装置4电连接,用于在处理器7的控制下驱动供排气装置4充气或放气。
在该血压测量设备中,在供排气装置4对气囊2进行充放气时,通过第二气压传感器5b来检测腔体101内的气压值,从而处理器7根据第二气压传感器5b检测的气压值以及存储的腔体气压值与气压补偿值的对应关系获得气压补偿值,再根据获得的气压补偿值对第一气压传感器5a检测的气压值进行补偿,得到较为准确的气囊2内的气压值。进而可以减小血压测量设备在充放气过程中对血压测量的影响,从而提高血压测量的精度。
本申请中,由于气腔内气体波动是由供排气装置4充放气产生的,距离供排气装置4越近的区域,产生的气压波动越大,因此,第二气压传感器5b可以靠近供排气装置4设置,第二气压传感器5b距离供排气装置4越近,测量结果越准确。
值得一提的是,图11所示的实施例的血压测量设备的其它结构均可参照上述任一实施例进行设置。例如,如图12所示,可以在血压测量设备中设置有气路腔体10,以使供排气装置4通过第一气路81与气路腔体10连通,使第一气压传感器5a可通过第二气路82与气路腔体10连通,并使气路腔体10通过第三气路83与气囊2相连通,以实现主体1和气囊2之间的单气嘴的连接。对于图11和图12所示的血压测量设备的其它结构的具体设置方式在此不进行一一赘述。
参见图13,图13为本申请实施例的一种血压测量设备的血压测量方法,在该血压测量设备中主要包括主体、气囊、第一气压传感器和第二气压传感器;其中,主体包括腔体,气压传感器位于腔体内,气囊具有气腔,气腔与腔体相连通,第一气压传感器用于检测气腔内的气压值,第二气压传感器用于检测腔体内的气压值。该血压测量设备的具体实施可 以参见上述图11和图12所示的实施例的血压测量设备,在此不作赘述。如图13所示,该血压测量设备的血压测量方法可以包括以下步骤:
步骤S301、获取血压测量设备进行充放气时第一气压传感器检测的气压值和第二气压传感器检测的气压值。
步骤S302、根据第二气压传感器检测的气压值以及存储的腔体气压值与气压补偿值的对应关系获得对应的气压补偿值。
步骤S303、根据获得的气压补偿值对第一气压传感器检测的气压值进行补偿。
由此可知,在进行血压测量时,可以根据第二气压传感器检测的气压值以及存储的腔体气压值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对第一气压传感器检测的气压值进行补偿,得到较为准确的气囊内的气压值。进而可以减小腔体内的气压对于血压测量的影响,从而提高血压测量的精度。
示例性的,腔体气压值与气压补偿值的对应关系也可以预先通过数据分析得到,并预先存储在血压测量设备中的处理器或存储器中,腔体气压值与气压补偿值的对应关系可以在血压测量设备出厂前通过处理器预先建立。
示例性的,如图14所示,处理器可以通过如下方式获得腔体气压值与气压补偿值的对应关系:
步骤S401、控制血压测量设备在卸除气囊时进行充气,以使第二气压传感器检测到的第一气压值发生变化。
将血压测量设备中的气囊卸除,可以使主体的腔体与外界大气连通,从而保证气压传感器检测的气压值不受气囊内气腔气压的影响,主要是由腔体内气流波动产生的。
在具体实施时,可以控制驱动装置由较小驱动功率逐渐增大至最大驱动功率来驱动供排气装置。
步骤S402、获取第二气压传感器在多个不同的第一气压值时第一气压传感器检测到的多个第二气压值,并将获取到的多个第二气压值作为多个不同的第一气体流量值分别对应的气压补偿值。
在具体实施时,可以在第二气压传感器检测到的第一气压值为q11时,获取第一气压传感器检测到的第二气压值q21,将q21作为q11对应的气压补偿值Δp1。然后增大驱动状态,至第二气压传感器检测到的第一气压值为q12时,获取第一气压传感器检测到的第二气压值q22,将q22作为q12对应的气压补偿值Δp2。以此类推,直到驱动装置达到最大的驱动状态,获取第二气压传感器检测到的第一气压值q1N,获取第一气压传感器检测到的第二气压值q2N,将q2N作为q1N对应的气压补偿值ΔpN。从而可以建立q11、q12、q13、q14、……、q1N与Δp1、Δp2、Δp3、Δp4、……、Δp N的对应关系。
步骤S403、根据多个不同的第一气压值和其分别对应的气压补偿值,建立腔体气压值与气压补偿值的对应关系。
示例性的,如图15所示,处理器可以根据多个不同的第一气压值和其分别对应的气压补偿值,通过插值法建立腔体气压值与气压补偿值的对应关系。例如,对于q11至q12、q12至q13、……、q1N-1至q1N之间的第一气压值q1(x),例如q1(x)位于q1i至q1j之间,那么q1(x)对应的气压补偿值Δp(x)可以根据公式Δp(x)=Δpi+[q1(x)-q1i](Δpj-Δpi)/(q1j-q1i)确定,其中,i可以取遍1至N-1中的任意数,j=1+1。
在具体实施时,在本申请中,对于位于0至q11、q11至q12、q12至q13、……、q1N-1 至q1N之间的第一气压值q1(x)所对应的气压补偿值Δp(x)也可以通过其它方式确认,在此不作限定。
由上述可知,正是存储了预先建立的腔体气压值与气压补偿值的对应关系,这样在进行血压检测时,就可以根据第二气压传感器检测的气压值以及存储的腔体气压值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对第一气压传感器检测的气压值进行补偿,得到较为准确的气囊内的气压值。其中,血压测量设备进行血压测量的流程可以包括:控制驱动装置驱动供排气装置向气囊充气,然后读取第一气压传感器检测的气压值和第二气压传感器检测的气压值,然后根据第二气压传感器检测的气压值以及存储的腔体气压值与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对第一气压传感器检测的气压值进行补偿,具体可以将第一气压传感器检测的气压值减去获得的气压补偿值从而得到补偿后的气压值,然后根据补偿后的气压值控制驱动电路的工作参数(例如电压,电流,频率等)驱动供排气装置向气囊充气。执行上述流程至少一次,例如1次、2次、3次或4次等,使补偿后的气压值满足血压测量所需的升压曲线要求,从而完成血压测量。
参照图16,图16为本申请又一种实施例提供的血压测量设备的结构示意图。该实施例的血压测量设备的结构与上述任意实施例也均有不同,其不同之处主要在于:在该血压测量设备中仅包括一个气压传感器,且不包括流量计。在该血压测量设备中,气压传感器5通过第二气路82与气囊2的气腔相连通,用于检测气腔内的气压值;处理器7与气压传感器5以及驱动装置6电连接,用于根据驱动装置6的驱动状态以及血压测量设备中存储的驱动状态与气压补偿值的对应关系获得气压补偿值,根据获得的气压补偿值对气压传感器5检测的气压值进行补偿,并根据补偿后的气压值控制驱动装置6;驱动装置6与供排气装置4电连接,用于在处理器7的控制下驱动供排气装置4充气或放气。
在该血压测量设备中,在供排气装置4对气囊2进行充放气时,由于处理器7可以根据驱动装置6的驱动状态以及存储的驱动状态与气压补偿值的对应关系获得气压补偿值,再根据获得的气压补偿值对气压传感器检测的气压值进行补偿,得到较为准确的气囊2内的气压值。进而可以减小血压测量设备在充放气过程中对血压测量的影响,从而提高血压测量的精度。
需要说明的是,驱动状态可以包括驱动电压、驱动电流、占空比等涉及供电功率的至少一个参数。
值得一提的是,图16所示的实施例的血压测量设备的其它结构均可参照上述任一实施例进行设置。例如,如图17所示,可以在血压测量设备中设置有气路腔体10,以使供排气装置4通过第一气路81与气路腔体10连通,使第一气压传感器5a可通过第二气路82与气路腔体10连通,并使气路腔体10通过第三气路83与气囊2相连通,以实现主体1和气囊2之间的单气嘴的连接。对于图16和图17所示的血压测量设备的其它结构的具体设置方式在此不进行一一赘述。
参见图18,图18为本申请实施例的一种血压测量设备的血压测量方法,在该血压测量设备中主要包括主体、气囊和气压传感器流量计;其中,主体包括腔体,气压传感器位于腔体内,气囊具有气腔,气腔与腔体相连通,气压传感器用于检测气腔内的气压值;该血压测量设备的具体实施可以参见上述图16至图17所示的实施例的血压测量设备,在此不作赘述。如图18所示,该血压测量设备的血压测量方法可以包括以下步骤:
S501、获取血压测量设备进行充放气时气压传感器检测的气压值以及血压测量设备的驱动状态。
S502、根据血压测量设备的驱动状态以及存储的驱动状态与气压补偿值的对应关系获得对应的气压补偿值。
S503、根据获得的气压补偿值对气压传感器检测的气压值进行补偿。
由此可知,在进行血压测量时,可以根据血压测量设备的驱动状态以及存储的驱动状态与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,得到较为准确的气囊内的气压值。进而可以减小腔体内的气压对于血压测量的影响,从而提高血压测量的精度。
在本申请中,驱动状态与气压补偿值的对应关系可以预先通过测试数据分析得到,并预先存储在血压测量设备的处理器或存储器中。
示例性的,在本申请中,如图19所示,处理器可以通过如下方式获得驱动状态与气压补偿值的对应关系:
步骤S601、控制血压测量设备在卸除气囊时以多个不同的驱动状态进行充气。
将血压测量设备中的气囊卸除,可以使主体的腔体与外界大气连通,从而保证气压传感器检测的气压值不受气囊内气腔气压的影响,主要是由腔体内气流波动产生的。
在具体实施时,可以控制驱动装置由较小驱动功率逐渐增大至最大驱动功率来驱动供排气装置4。
步骤S602、获取血压测量设备以多个不同的驱动状态进行驱动时气压传感器检测到的多个气压值,并将获取到的多个气压值作为多个不同的驱动状态分别对应的气压补偿值。
在具体实施时,可以在驱动功率为S1时,获取气压传感器检测到的气压值q1,将q1作为S1对应的气压补偿值Δp1。然后增大驱动功率至S2时,获取气压传感器检测到的气压值q2,将q2作为S2对应的气压补偿值Δp2。以此类推,直到驱动装置达到最大的驱动功率SN,获取气压传感器检测到的气压值qN,将qN作为SN对应的气压补偿值ΔpN。从而可以建立S1、S2、S3、S4、……、SN与Δp1、Δp2、Δp3、Δp4、……、Δp N的对应关系。
步骤S603、根据多个不同的驱动状态和其分别对应的气压补偿值,建立驱动状态与气压补偿值的对应关系。
示例性的,参见图20,处理器可以根据多个不同的驱动状态和其分别对应的气压补偿值,通过插值法建立驱动状态与气压补偿值的对应关系。以驱动状态为驱动功率为例,例如,对于S1至S2、S2至S3、……、SN-1至SN之间的驱动功率S(x),例如S(x)位于Si至Sj之间,那么S(x)对应的气压补偿值Δp(x)可以根据公式Δp(x)=Δpi+[S(x)-Si](Δpj-Δpi)/(Sj-Si)确定。其中,i可以取遍1至N-1中的任意数,j=1+1。
在具体实施时,在本申请中,根据S1、S2、S3、S4、……、SN与Δp1、Δp2、Δp3、Δp4、……、Δp N的对应关系,也可以通过其它方式建立驱动状态与气压补偿值的对应关系,在此不作限定。
由上述可知,正是存储了预先建立的驱动状态与气压补偿值的对应关系,这样在进行血压检测时,就可以根据驱动状态以及存储的驱动状态与气压补偿值的对应关系来获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,得到较为准确的气囊内的气压值。其中,血压测量设备进行血压测量的流程可以包括:控制驱动装置驱动 供排气装置向气囊充气,并读取气压传感器检测的气压值,然后再根据驱动装置的驱动状态以及存储的驱动状态与气压补偿值的对应关系获得气压补偿值,根据获得的气压补偿值对气压传感器检测的气压值进行补偿,具体可以将气压传感器检测的气压值减去获得的气压补偿值从而得到补偿后的气压值,然后根据补偿后的气压值控制驱动电路的工作参数(例如电压,电流,频率等)驱动供排气装置向气囊充气。执行上述流程至少一次,例如1次、2次、3次或4次等,使补偿后的气压值满足血压测量所需的升压曲线要求,从而完成血压测量。
综上,采用本申请提供的血压测量设备进行血压测量时,可以根据获得的气压补偿值对气压传感器检测的气压值进行补偿,从而可以有效的减小血压测量设备的主体的腔体内的气压对气压传感器的测量值的影响,从而使血压测量结果较为准确。
相应地,本申请实施例还提供了一种电子设备,该电子设备可以包括上述实施例提供的任一种血压测量设备。由于该电子设备解决问题的原理与前述一种血压测量设备相似,因此该电子设备的实施可以参见前述血压测量设备的实施,重复之处不再赘述。
以上,仅为本申请的具体实施方式,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以权利要求的保护范围为准。
